Sick or not? The green light will tell.

A US company has developed a bright green LED light, which is attached to the animal’s ear and is able to warn the farmer if an animal is sick.


Pulling cattle out of large feedlots for treatment can be time consuming, provided you even know these animals are sick.

Quantified Ag, based in Lincoln, Nebraska have therefore developed a light to attach to the cow’s ear that turns bright green when the animal is sick.

The concept has been tested in US feedlots and is set to launch commercially soon.

RESEARCH: LED lighting could have major impact on wildlife.

RESEARCH: LED lighting could have major impact on wildlife. New research by the University of Exeter and published in global change biology shows that LED street lighting can be tailored to reduce its impacts on the environment. The UK-based study found predatory spiders and beetles were drawn to grassland patches lit by LED lighting at night, but the number of species affected was markedly reduced when the lights were dimmed by 50% and switched off between midnight and 4am. LEDs made up just 9% of the global lighting market in 2011, but forecasts suggest they will account for 69% by 2020. RESEARCH: LED lighting could have major impact on wildlife. The growth of LED lighting is an issue of global concern, and the number of documented impacts on the environment is growing rapidly. The research shows that local authorities might be able to manage LED lighting in a way that reduces its environmental impacts. There is a need to establish whether this is the case for a greater variety of species. The results suggest that the growing use of LED lighting will have impacts on the abundance of predatory invertebrates, potentially leading to knock on effects for other species in grassland food-webs.

Light-activated glue to replace sutures..

A scientist has developed a glue that could mean the end of sutures. Maria Pereira has created a surgical glue that can mend broken hearts. Sutures are time-consuming, damage tissue and are technically challenging," says Maria Pereira, head of research at Paris-based Gecko Biomedical, whose bio-inspired alternative it says can replace stitches. Its adhesive is viscous, hydrophobic, biodegradable and cured by LED light. Unlike other glues, which can be washed away by water, it can be placed in wet environments such as the heart, where 
it works as both a sealant and a scaffold for tissue to grow over. Pereira, 30, invented the glue in 2010 while a bioengineering PhD student in the MIT Portugal Program. Doctors at Boston Children's Hospital had approached her supervisor, Jeff Karp of the Harvard-MIT Division of Health Sciences and Technology, with a problem: how to close defects in a newborn baby's heart without sutures. A newborn's heart is as large as its fist, so operations are extremely delicate. Pereira looked to nature for inspiration. "Understanding the basic principles 
of how things work is very important in developing new technologies," she says. Her sealant can stay sticky inside a beating pig's heart by mimicking the viscous, hydrophobic secretions of snails and sandcastle worms. This breakthrough as published in the wired states that Karp and a group of prominent scientists and entrepreneurs founded Gecko Biomedical in 2012, hiring Pereira as head of research. The first product made from the adhesive, GB02, acts as an adjunct to sutures in vascular reconstruction surgery and will go into clinical trials this spring, with the aim of securing regulatory approval in the first half of 2017. The goal of the company is to make surgery simpler and to change how it is done, the company is also working on another product GB04, which could end the need for sutures altogether.

HORSY INNOVATION.

An accident while trotting down the street on a horse, brought on a mission to develop an innovated light safety system. The system showcases LED lights, on both the front and tail units to warn, oncoming motorists that there is a rider on the road.Read more; http://www.dailymail.co.uk/sciencetech/article-3327748/That-really-tail-light-Firm-unveils-clips-light-horses-improve-rider-safety.html
